Specification of Letters Patent.

Patented Feb. 24; 1914;.

To all whom it may concern: 1

Be it known that I, ALFRED W. F. GUEST, a citizen of the United States,residing at Brooklyn, in the count-y of Kings and State of New York,have invented certain new and useful Improvements in TypographicalMachines, of which the following is a specification, reference being hadtherein to the accompanying drawing.

My invention relates to typographical machines, such as linotypemachines of the general organization re resented in Letters Patent ofthe United tates, No. 436,532, to O. Mergenthaler, wherein circulatingmat rices are released from a magazine in the order in which theircharacters are to appear in print and then assembled in line, thecomposed line transferred to the face of a mold, the mold filled withmolten metal to form a slug or linotype against the matrices whichproduce the type characters thereon, and the matrices thereafterreturned through a distributing mechanism to the magazine from whichthey started.

More particularly, it relates to machines of the kind illustrated forinstance in Letters Patent of the United States,-No. 547,633, to P. T.Dodge, wherein the matrices are each formed with a plurality ofcharacters, and means are provided for presenting the matrices at onelevel or another to the mold, so that the cast may be made from one oranother set of the characters thereon. My present improvements aredesigned to change the level of the matrices for this general purpose,when desired, and to this end I preferably provide the intermediatechannel, through which the matrices are transferred, with appropriateshifting or switch mechanism, operable at will.

In the accompanying drawings, I have illustrated my invention inpreferred form and by Way of example, and as applied to a linotypemachine, but obviously many variations and modifications may be madetherein, and in its mode of application, which will still be comprisedwithin its spirit.

Generally speaking, I desire it to be understood that I do not limitmyself to any specific form or embodiment, except in so far as suchlimitations are specified in the claims.

In the accompanying drawings: Figure 1 1s a front view of a portion ofthe machine, partly broken away, with my invention applied thereto; Fig.2 is a perspect1ve view of the intermediate channel, partly broken away;Fig. 3 is a front view of the intermediate channel, partly broken away,and showing the switch in operation; and Fig. a is a section, takensubstantially on the line 4=4 in Fig. 3.

The matrices X and spacers Y are delivered to the assembler A, and afterthe line is composed, the assembler is raised to introduce the linebetween the fingers B, B connected to the slide C, whereby the line istransferred through the intermediate channel D to the first elevator E,by which it is lowered into operative relation to the mold F. The partsand their mode of operation,

' so far described, are or may be substantially like those presented inthe Letters Patent previously mentioned. As in the said Dodge patent,the first elevatorE is provided with means for supporting the matricesat dif ferent levels, so that one set or another of the charactersthereon may be presented in operative relation to the mold. Thesesupporting means are not shown herein, but are or may be of the usual orany desired form.

For purposes of description, it may be assumed that the matrices are allassembled at the same level in the assembler A, and that it is desiredto shift them to the elevator E at one or another level, so as to bringthe corresponding line of characters into operative relation to the moldF. This determination of level I preferably effect while the line isbeing transferred through the intermediate channel I). This channel isformed with the customary ledges G, which normally engage under theupper ears of the moving matrices X and thus support them, their lowerears passing under the ledges H therein. If the matrices are transferredto the elevator in this position, which is their lower level, theirupper line of characters will be presented to the mold and the slug willbe cast therefrom in the and preferably at its end and in proximity tothe elevator E, isa pivotally-mounted plate or switch 5', which in itsnormal position (see Fig. l) constitutes in ehect a continuation of oneof the ribs H. In these circumstances, and'as indicated in Fig. l, thematrices will pass to the elevator without change of level, as theirlower ears willride under the switch J, and theywill he held downthereby. If it be desired to transfer the matrices to the elevator at ahigher level, the switch J is turned downward, to the position shown inFigs. 2 and 3, when the lower ears of the matrices will engage over thepoint thereof and be elevated thereby to their upper position in theelevator E.

For the convenient manipulation of the switch J, it is preferablyprovided with an arm and finger piece K, and. a pin L adapted. to engagea hole in the ch nnel D to hold the switch in its normal position.

Although l have illustrated and described my invention as applied tothat style of composition where all the matrices are assembled at acommon level, and connection with means whereby they may be transferredto the first elevator at one oftwo levels, it will be obvious that I. amnot limited to such a specific arrangement or mode. of operation.

As previously stated, l have illustrated my invention only in preferredform and by way of example, and hbviously many variations andmodifications in the particular construction, and in the application ofits principles to other conditions, will suggest themselves to thoseskilled in the art, without departure from its scope.

Having thus described my invention, its

construction and mode of operation, what I claim and, desire to secureby Letters Patent of the United States is, as follows:

1. In a typographical machinecomprising plural letter matrices, thecombination of means for assembling the matrices at a com mon level andmeans for presenting them to the casting mechanism at different levelsto bring one or another set of characters into operative position, thesaid presenting means including an intermediate channel through whichthe matrices are transferred, and devices cooperating with the matricesto bring them from their common assembled level to the desired levelduring their passage therethrough.

2. In a typographical machine comprising plural letter matrices, thecombination of means for assembling the matrices at a common level andmeans for presenting them to the casting mechanism at different levelsto messiah bring one or another set of characsers into operativeposition, the said presenting means including an intermediate channelthrough which the matrices are transferred, and the movable switch J tobring the matrices from their common assembled level to the desiredlevel during their passagethrough the said channel.

3;. In a typographical machine comprising plural letter matrices, theco. hination of means for assembling the matrices a common level andmeans for presenting the the casting mechanism at different le bring oneor another set of Chill: operative position, the said present: gincluding the intermediate channel the adjustable switch J, so that inone position of the switch the ears of the matrices will pass thereunderfrom their common as sembled level to one of said levels, and in anotherosition thereof will ass thereover to another of said levels.

l. ln a typographical machine comprising plural letter matrices, thecombination of means for assembling the matrices at a common level andmeans for presenting them to the casting mechanism at different levelsto bring one or another set or characters into operative position, thesaid presenting means including the intermediate channel D formed withthe ledge H and the adjustable s vitch J, which in one positionconstitutes a continuation of the ledge so that the ears of the matricesWill pass thereunder from their common assembled level to one of said p,levels, and in another position engages beneath the ears of the matricesto elevate them to another of said levels.

5. in a typographical machine comprising plural letter matrices, thecombination of means for assembling the matrices at a common level andmeans for presenting them to the casting mechanism at different levelsto bring one or another set of characters into operative position, thesaid presenting means including the first elevator E and devices tocooperate with the matrices after they have left the assembling means attheir common assembled level and deliver them to the first elevator atone or another of said levels.

In testimony whereof I aflix my signature in presence of two Witnesses.

ALFRED W. F GUEST.
